Based on characters from the hit theatrical film Legion (2010), Dominion is an epic supernatural drama set in the year 25 A.E. In this transformed post–apocalyptic future an army of lower angels, assembled by the archangel Gabriel, has waged a war of possession against mankind. The archangel Michael, turning against his own kind, has chosen to side with humanity against Gabriel. Rising out of the ashes of the 25 year-long battle are newly fortified cities which protect the human survivors. In Vega (formerly Las Vegas), the largest of these cities, two houses vie for control and the stage is set for political upheaval and a dangerous power shift. Meanwhile, a rebellious young soldier begins a perilous journey as the war between the human race and the fallen angels hell-bent on their domination escalates.

Dominion, produced by Universal Cable Productions and Bold Films, is in production in Cape Town, South Africa. The series is executive produced by Vaun Wilmott, Todd Slavkin & Darren Swimmer, along with Executive Producers Scott Stewart, who co-wrote and directed the feature film Legion, Michael Litvak and David Lancaster of Bold Films who produced the original film.
